Today, how can we position their future in a context of significant environmental and social change? In order to address the notions of viability and coviability, it is necessary to verify the study's systemic context. The hypothesis that an oasis system exists has thereby been tested and the analytical inferences discussed. It uses the systemic approach and relies on reasoning by compartmentalization which is useful in the case of complex systems. Through a dual compartment/system vision, it is possible to address the trajectory of the North African oases, presented here as territorial compartments, to discuss their systemic coherence and thus question their future. This work illustrates a generic approach in order to understand the society-environment relationship. It provides the suitable systemic level for governance targeting systemic viability and coviability. %$ 021ENVECO
